Title: Method for coloring surface of metal
Inventor: KITANI SHIGERU
IPC: C25D21/00
Filed: 1986-08-30
Abstract: PURPOSE:To arbitrarily color the surface of a desired metal patternwise, independently of the kind of metal with a small loss of electric current used by bringing the surface of the metal to be colored into contact with an electrolyte soln. and placing an electrode having no electrical direct connection with the metal near the metal. CONSTITUTION:The surface of a metal or alloy 4 to be colored is brought into contact with an electrolyte soln. 1 and an electrode (cathode) 5 having no electrical direct connection with the metal 4 is placed near the metal 4. Thus, a colored film is formed on the surface of the metal 4 by oxidation without directly supplying electric current to the metal 4. In this case, one side of the metal 4 confronting the electrode 5 is colored according to the electrode 5, and the other side is colored by bringing a positively charged electrode (anode) 6 close to the metal 4. The coloring effect is easily produced by holding the metal 4 between the cathode 5 and the anode 6 at narrow intervals.

Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To improve the resolution and detecting accuracy of a piezoelectric vibrational angular velocity meter even when the size of the meter is reduced by arranging the columnar vibrator of the meter along the diagonal line of a substrate. SOLUTION: A columnar vibrator 1 is formed by sticking two PZT (lead titanate zirconate) piezoelectric members to each other with a reference electrode in between and provided with a driving electrode which excites the vibrator 1 and a detecting electrode and a feedback electrode which are respectively attached to both ends of the vibrator 1.
